Even worse for the third-ranked Orange, they were seconds away from a ninth straight victory.

Ryan Arcidiacono spoiled those plans with the tying 3-pointer with 2.2 seconds left in regulation, and James Bell hit consecutive 3s in overtime to send Villanova to its second win over a Top 5 team this week, 75-71.

The Wildcats defeated No. 5 Louisville 73-64 on Tuesday and became the first unranked team to beat two Top 5 teams in the same season since Florida State in 2011-12, according to STATS LLC.

“We couldn’t get going offensively for a long time,” coach Jim Boeheim said. “We hung in there and battled.”

The Wildcats (13-7, 4-3) took advantage with Syracuse’s rough night from the field.

Arcidiacono’s 3-point attempt to tie with about 25 seconds left in regulation was off the mark. Carter-Williams missed the front end of a 1-and-1 and JayVaughn Pinkston of the Wildcats grabbed the rebound.

Bell missed a 3 and Mouphtaou Yarou grabbed the offensive rebound. Syracuse decided not to foul, giving Yarou time to kick it out to Arcidiacono. He let go a leaner from just beyond the 3-point line to tie the game at 61, force overtime and send the crowd of 18,273 into a frenzy.

“I just put it up and luckily it went in,” Arcidiacono said. “I think we’re having fun.”

The Wildcats may not be ranked in next week’s AP Top 25 poll, but they have worked their way into NCAA tournament consideration.

“What a week for us,” coach Jay Wright said.

What an understatement.

Philadelphia’s college fans came down with a case of court-storming fever this week after Villanova’s win over Louisville and La Salle’s 54-53 win the next night over No. 9 Butler. At the Wells Fargo Center, home of the NHL’s Flyers, the fans made it a Philly hoops hat trick, rushing the court in celebration of perhaps the biggest regular-season week in Villanova history.

With the Orange down two points in overtime, Triche made one free throw with 46.5 seconds left.

Bell followed with a layup to for a 71-68 lead and the Wildcats (13-7, 4-3) held on from the free throw line.

“It stinks, but hopefully we play them again in the Big East tournament,” Carter-Williams said.

Darrun Hilliard scored 25 points had six assists and no turnovers in 38 minutes. Yarou had 14 points and 16 rebounds for the Wildcats while Bell scored 13 points. The Wildcats committed only one turnover in the final 14 minutes.

Yes, this is the same team that lost consecutive games to Alabama, Columbia and La Salle in November. There’s no break on the schedule, either: Villanova plays Wednesday at No. 24 Notre Dame.

“It takes time to build a team,” Wright said. “That’s what we’re doing here. We’re building a team.”

The Orange clearly could have use James Southerland in the tight game. Southerland, second on the team in scoring at 13.6 points and the team leader with 33 3-pointers, was declared out indefinitely because of an eligibility matter involving academics that has yet to be resolved.

Jerami Grant, who played well in Southerland’s absence, hit a 3-pointer early in the second half that gave the Orange their first lead of the game, 33-32. Grant fouled out with 5:22 left and the Orange up one. His fifth foul was against Hilliard. Hilliard missed both from the line, the Orange stormed down in transition off the defensive board, and Triche hit a 3 for a 57-53 lead.

The Orange just could never put them away. They missed six of eight shots in overtime and were only 5 of 14 overall from 3-point range.

“We played good D but their point guard just made a good shot to send it to overtime,” forward C.J. Fair said. “I knew we had a shot at coming back and winning this game. It just didn’t bounce our way.”

Triche, a 50 percent shooter on the season, hit Syracuse’s first 3-pointer of the half to slice the lead to four. He tipped in a basket at the buzzer to cut the lead to 32-26.

“We missed a lot more layups than we have all year,” Boeheim said. “That’s part of the game.”

GEORGETOWN 53, No. 5 LOUISVILLE 51

WASHINGTON — Otto Porter had 17 points and grabbed the game’s decisive rebound with 1.4 seconds to play as Georgetown handed Louisville its third straight loss.

Trailing by one, Louisville had several chances to take the lead in the final 2 minutes. After getting the ball back on a disputed held ball ruling, the Cardinals kept the ball for a final shot. Peyton Siva, who didn’t score in the game, missed the jumper, Porter grabbed the rebound and was fouled.

Porter finished with 12 rebounds for the Hoyas (14-4, 4-3 Big East).

Russ Smith, taken out of the starting lineup, finished with 12 points, while Luke Hancock and Gorgui Dieng also had 12 for the Cardinals (16-4, 4-3), who have their longest losing streak since January 2010. No. 1 in the country a week ago, Louisville then fell to Syracuse and Villanova.

No. 6 ARIZONA 74, USC 50

TUCSON, Ariz. — Nick Johnson scored 14 points and No. 6 Arizona used a stifling defense to bounce back from a home loss and rout Southern California 74-50 on Saturday night.

The Wildcats (17-2, 5-2 Pac-12) were dominant from the opening tip, jumping out to leads of 18-4 and 29-7. They were up 39-20 at halftime.

The Trojans (8-13, 3-5), who shot 28 percent, trailed by as many as 34 in the second half.

USC dropped to 1-3 since Kevin O’Neill was fired and replaced by interim coach Bob Cantu. The other two losses were by one point to Oregon and 98-93 in overtime Thursday night at Arizona State.

This one was a blowout in a hurry.

The Wildcats, who fell behind UCLA 21-5 in Thursday night’s 84-73 home loss to the Bruins, turned the tables on the Trojans.

USC made two of its first 19 shots and committed seven turnovers, allowing Arizona to go up 29-7 on Hill’s layup with 7:55 left in the half, the last points in an 11-0 Wildcats run.

When the Trojans managed to cut it to 36-20 with a pair of baskets in the final minute, Mark Lyons sank a 3-pointer from the top of the key 2 seconds before the buzzer to make it 39-20 at the break.

Arizona never led against UCLA, and never trailed in this one.

Johnson scored eight as the Wildcats streaked to a 12-2 lead, then consecutive 3s by Lyons and Parrom put them ahead 18-4.

The 20 points at the half were the fewest this season for the Trojans, who had averaged 72.4 points in their first seven conference games.

USC “warmed up” to 24 percent shooting in the first half (7 for 29), compared with 48 percent for Arizona (14 for 29).

But the second half started the same way the first did, with the Trojans making three of their first 20 shots. Arizona, meanwhile, took a 58-27 lead when Johnson banked in a 15-footer with 10 minutes to play.

USC was able to cut into the lead only when Arizona coach Sean Miller emptied his bench in the final 3 minutes.

USC’s three-guard starting trio of J.T. Terrell, Byron Wesley and Renaldo Woolridge were a combined 5 for 26 from the field, 3 of 11 on 3-pointers.

UCLA followed its big win in Tucson on Thursday with a loss at Arizona State on Saturday.

The Gators (16-2, 6-0 Southeastern Conference) have now won eight straight and were never challenged in this one, bolting out to a 20-6 lead in less than eight minutes and a 41-19 advantage by halftime.

Florida hit a season-high 14 3-pointers, including four each by Boynton and Murphy. Boynton finished 7 of 11 from the field and 4 of 8 from 3-point range. The Gators shot 31 of 56 (55.4 percent) from the field.

Fred Thomas led Mississippi State (7-11, 2-4) with 19 points. Colin Borchert and Gavin Ware both added 10. The Bulldogs have lost four straight.

No. 10 GONZAGA 66, SAN FRANCISCO 52

SPOKANE, Wash. — Kelly Olynyk scored 13 points, helping No. 10 Gonzaga extended its home winning streak against San Francisco to 24 games with a 66-52 victory on Saturday night.

Elias Harris had 12 points and 11 rebounds for Gonzaga (19-2, 6-0 West Coast Conference) and Kevin Pangos added 11 points. Gonzaga made 45 percent of its shots and was 8 of 20 from 3-point range.

Chris Adams led San Francisco (9-12, 2-6) with nine points and Avry Holmes scored eight. The Dons turned the ball over 17 times and were 9 of 24 from behind the arc.

Gonzaga built a 43-21 halftime lead, but started out sloppy in the second half. The Bulldogs made only one basket in the first four minutes.

IOWA STATE 73, No. 11 KANSAS STATE 67

AMES, Iowa — Will Clyburn had 24 points and 10 rebounds and Iowa State handed Kansas State its second straight loss.

Freshman Georges Niang added 15 points for the Cyclones (14-5, 4-2 Big 12), who beat a ranked opponent for the first time this season.

Will Spradlin had 15 points and Rodney McGruder scored 13 to lead the Wildcats (15-4, 4-2), who lost on the road for the first time in four tries.

MADISON, Wis. — Traevon Jackson just beat the shot clock and hit a 15-foot jumper from the right side with 4 seconds left as Wisconsin handed Minnesota its fourth straight loss.

After Jackson’s shot gave the Badgers a 45-43 lead, the Golden Gophers (15-5, 3-4 Big Ten) called a timeout with 1.8 seconds remaining and inbounded from halfcourt. The Badgers’ Mike Bruesewitz fouled Trevor Mbakwe on the play, but the big man was unable to shoot the ensuing free throws because of an apparent right hand or wrist injury.

Rodney Williams stepped to the line and made the first free throw, but missed the second and Sam Dekker grabbed the rebound to seal the win for Wisconsin (14-6, 5-2), which ended a two-game slide.
